You only have a certain amount of energy, and when you spread it around, everything gets confused, and the first thing you know, you can't remember which one you've told which story to, and the next thing you know, you're moaning "Oh, Morty, Morty, Morty," when what you mean is "Oh, Sidney, Sidney, Sidney," and the next thing you know, you think you're in love with both of them simply because you've been raised to believe that the only polite response to "I love you" is "I love you too," and the next thing you know, you think you're in love with only one of them, because you're too guilty to handle loving them both.
